Application March 20, 1950, Serial No. 150,723

3 Claims. (cl. 16202) The invention has reference generally to improvements in means for coupling sash weight cords and the like to window sashes.

It has for an object to provide a fixture of this nature which may readily and quickly be attached to the window sash prior to installation of the same in its frame; and when thus installed serving for ready and convenient replacement of a sash chain or cord without the necessity of then removing or in any way disturbing any part of the sash or window frame for attachment of the cord to said sash. It will, of course, be understood that the customary pocket cover in the pulley stile is to be removed for access to the sash weight. The installation of the fixture may be effected, also, without marring or defacing the sash to any appreciable degree.

A further object of the invention is to provide a simple, inexpensive fixture applicable to the sash without the use of tools other than a hammer or screw driver.

In carrying out the invention, the novel fixture is provided in two parts, one constituting a guide strip or member attachable to the face of the stile running in the frame groove and a cord attachment slidable element adapted to be mounted in the guide for movement relative thereto. The said slide element is provided also with means automatically securing the guide strip and slidable element to each other when assembled for use. In addition, the slide element bears at its lower end a resilient tongue to receive the sash chain end which is looped thereover or, in the case of cord, to receive a clip provided on the end of the cord. The said guide strip may be provided with perforations for nails or screws in securing the strip to the stile or integral spurs may be formed therefrom to be driven into the stile.

The nature of the invention, however, will best be understood when described in connection with the accompanying drawings, in which:

Fig. 1 is a fragmentary inside elevation of a window showing the sashes and with the pocket cover removed and portion of the frame shown in broken-out section to illustrate the novel fixture as installed on the stile of one of the window sashes.

Fig. 2 is a perspective view of the novel fixture; and Fig. 3 is a transverse vertical section thereof taken on the line 3--3, Fig. 2, and looking in the direction of the arrows.

Fig. 4 is a perspective view of a modified form of the fixture; and Fig. 5 is a transverse vertical section thereof taken on the line 5-5, Fig. 4, and looking in the direction of the arrows.

Fig. 6 is a front elevation of the modification shown in Figs. 4 and 5 with the guide portion broken out in section.

Fig. '7 is a perspective view illustrating a still further modification in the fixture; and Fig. 8 is a transverse vertical section taken on the line 8-8, Fig. 7, and looking in the direction of the arrows.

Fig. 9 is a fragmentary enlarged vertical section of the upper end of the form of fixture ilustrated in Figs. 7 and 8.

Fig. 10 is'a fragmentary perspective view of the upper end of a modification in the arrangement of the means for holding normally the cooperating elements of the fixture to each other; and Fig. 11 is a fragmentary transverse vertical section taken on the line Illl, Fig. 10, and looking in the direction of the arrows.

Fig. 12 is a fragmentary rear elevation of the fixture shown in Figs. 10 and 11.

Referring to the drawings, more particularly Fig. 1 thereof, Iii designates one side of a window frame in which are mounted the lower sash II and upper sash I2, said sashes being mounted to slide in the ordinary manner between suitable stops and parting beads as is well understood.

In carrying out the invention, the novel chainor cord-retainer fixture is shown, for simplicity, attached only to the lower sash, but it will be understood that similar provision is to be made in connection with both of the sashes. As indicated, the fixture I3 is fixedly secured, that is by nailing or screwing the same, to the outer surface of the stile l4, its upper end extending in close proximity to the top rail [5 of the sash II in order that its slidable element will be conveniently accessible for manual withdrawal in attaching the free end of the chain or cord, as will hereinafter be more fully set forth.

The fixture is shown more particularly in Figs. 2 and 3 wherein a guide or channelled member I6 is provided, the same being designed to be fixedly secured to the stile, as hereinbefore noted, and is adapted to receive a chainor cord-receiving element ll which is slidable in the guide. This element may be provided at its upper end with a forwardly-directed, turned-over lip I8 for use in withdrawing the slide and intended, when the fixture has been installed, to project beyond the upper end of the guiding channel member as well as slightly above the top rail of the sash. Its position in this respect may be secured by a spur l9, rearwardly directed from the element ll,

'member 35 is designed to slide.

which is designed to register with and snap into an opening in the bottom of channel member IS. The element H to this end is under a slight spring pressure provided by the spring 2| secured to the channel and bearing upon said ele-- ment l1.

At its lower end,.the element I1 is provided with a holding means such as the more or less resilient downwardly directed hook 22 over which is to be fitted the lower; end of the chain or, in the caseo'f' a cord, 2. terminal clip or lug (not shown) provided thereover. When the fixture.

is thus secured to the stile of a sash, should the chain or cord break, it would be buta simple,

matter to press slightly forward at its upper end the element I! to release it from its locked position in the channel member l6 and, by grasping returned to its channel member and depressed until spur l9 snaps into the opening 20.

In Figs. 4-6, inclusive, a modification in the means for securing. a slide element 25 in its channel member 26 is indicated. In this embodiment the slide element at its upper end is reduced in width from the lip 21 downwardly a short distance and provided at the lower end of the reduced portion along one edge with a tooth or detent 28 designed to fit through a hole 23 provided. in one of the sides. of the channel, the slide .elementas a whole being urged resiliently toward said opening by. means of a spring 3!! engaging with the edge of the slide element opposite the 'edge provided. with the tooth. In order then to release the slide element for withdrawal, it is necessary merely to exert a lateral pressure thereon in a direction against the action of spring 30 to release the tooth 28 from hole 29. Uponreturning the slide element after a broken chain or cord has been replaced by attaching its. end to hook 3|, tooth 28 will automatically enter the hole 29. In this connection, there-is provided, also, at the bottom of the channel member a, spur 32 struck therefrom outwardly to engage the lower edge 33 of the slide element and thus limit its downward movement.

Figs. 7, 8V and 9 illustrate a slightly different detent arrangement, the same being carried also "by the. slide element. In this embodiment the slide element 35 carries at its upper end a detent member pivoting about a supporting pin 36 extending from the bottom of the slide element. This. detent member is provided with an operating arm 31 extending outwardly beyond the top of the. fixture when the same is properly assembled and is designed to rock the detent memher about pivot 36 to permit a tooth 38 of said detent member to be withdrawn from hole 39 in the side of the. channel. member 4.0. in. which the A spring 4| located between the detent member and the bottom. of slide 35 normally urges the detent member in.a direction such that its tooth would pass through the opening 39.. To withdraw the. slide 35 from its channel member an, it is necessary merely tov rock the operating arm. 3! inwardly, which. will releasethe tooth from the hole 39 and There-- permit the slide 35 to be withdrawn. In returning the slide to its channel member, the two are automatically looked under the action of spring GI when the tooth 38 and hole 39 register. A stop lip 42 at the bottom of the channel mem ber checks the downward movement of said slide element.

Another means of securing a slide member to its channel during normal conditions is indicated in Figs. 10-12, inclusive. In this embodiment, the rear of the channel 45 in which slide 46 operates is provided at its top with one or more expanded and staggered semi-circular holding. members 41 adapted to have threaded therein a metal screw 48. This screw is designed to pass through a backwardly-turned lip 49' of the slide element 45 and is provided with the opening 50. When the screw then is passed through 'both the lip and the holding members 41, the slide element and channel member are substantially locked together, but the former may readily be removed from the latter by removing the screw 48- and then withdrawing said slide for replacement of the chain or cord.

I claim:

1. A sash weight cord connector comprising a guide strip element adapted to be fixed to the outer edge of the sash stile, and an attachment element slidable therein and provided with means for receiving a sash. weight cord, and means integral with one ofsaid elements adapted for locking engagement normally solely with the other element, said attachment element including a portion located for manual actuation at its upper end in close proximity to the upper rail of the sash to release temporarily said attachment element from the said guide strip, and resilient means urging the elements into contact with each other.

2. The combination according to claim 1, wherein the upper end of the guide strip element is provided with an opening and the attachment element is provided with a rigid integral spur directed, when the strip and attachment elements are assembled, toward the juxtaposed face of said guide strip element and to fit solely into the opening thereof When said spur and opening are juxtaposed.

3-. The combination according to claim 1, wherein the guide strip element is a channel and provided with an opening in one side Wall thereof, and the upper end of the attachment element has a tooth along one longitudinal edge for engagement solely with said opening, and resilient means extend from the other side wall of the channel for engagement with the other longitudinal edge of the attachment element to urge t'he'latter into contact with the channel element.
